The Healthy Hip
The hip joint is a load-bearing ball-and-socket joint that relies on surrounding muscles, ligaments, and connective tissues for proper function. Here is a brief overview of the properties of a healthy hip:
- The human hip is composed of the head of the thigh bone (femur) and the socket (acetabulum) of the pelvis.
- These bones are held together by tendons and ligaments, and separated by a shock-absorbing layer of smooth articular cartilage called the labrum.
- The labral cartilage allows the acetabulum to roll over the femoral head with little resistance.
Problems of the Hip
Common problems experienced in the hip include:
- Osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis
- Labral tear or other articular cartilage injury
- Bone fracture from age or injury
- Trochanteric bursitis, an inflammation of the cover of the point of the hip
- Swollen or inflamed synovial membrane, the lining of the joint
For patients dealing with labral tears, osteoarthritic cartilage damage, trochanteric bursitis or bone fractures, mesenchymal stem cell hip injections can be used in conjunction with platelet-rich plasma (PRP) injections to decrease pain and increase in joint mobility and function.
